Closing the Gap to the Capacity of APSK: Constellation Shaping and Degree Distributions
Xingyu Xiang, Matthew C. Valenti
Constellation shaping is an energy-efficient strategy involving the transmission of lower-energy signals more frequently than higher-energy signals. Previous work has shown that sh…
A New Analysis of the DS-CDMA Cellular Downlink Under Spatial Constraints
Matthew C. Valenti, Don Torrieri, Salvatore Talarico
The direct-sequence code-division multiple access (DS-CDMA) cellular downlink is modeled by a constrained random spatial model involving a fixed number of base stations placed over…
Distributed Estimation of a Parametric Field Using Sparse Noisy Data
Natalia A. Schmid, Marwan Alkhweldi, Matthew C. Valenti
The problem of distributed estimation of a parametric physical field is stated as a maximum likelihood estimation problem. Sensor observations are distorted by additive white Gauss…
The Outage Probability of a Finite Ad Hoc Network in Nakagami Fading
Don Torrieri, Matthew C. Valenti
An ad hoc network with a finite spatial extent and number of nodes or mobiles is analyzed. The mobile locations may be drawn from any spatial distribution, and interference-avoidan…
Analysis and Optimization of a Frequency-Hopping Ad Hoc Network in Rayleigh Fading
Salvatore Talarico, Matthew C. Valenti, Don Torrieri
This paper proposes a new method for optimizing frequency-hopping ad hoc networks in the presence of Rayleigh fading. It is assumed that the system uses a capacity-approaching code…
Optimization of a Finite Frequency-Hopping Ad Hoc Network in Nakagami Fading
Matthew C. Valenti, Don Torrieri, Salvatore Talarico
This paper considers the analysis and optimization of a frequency-hopping ad hoc network with a finite number of mobiles and finite spatial extent. The mobiles communicate using co…
